WebFor example, in polyvinyl chloride, the degree of rotation of the polar groups about the C–C axis depends on the position and the angle of the section of the C–C links. If a system has more than one type of dipole, the relaxation times will be distributed. Supposing that N is the number of dipoles of one type per unit volume, than we can write Webμ = Induced dipole moment α = Polarizability E = Electric field The interaction energy can be calculated with the help of London dispersion force formula. V 11 = – 3 α 2 I 4 r 6 This formula is for the potential energy between two identical atoms or molecules.
